2013MBA联考英语试卷(附答案)_2

2013MBA联考英语试卷(附答案)_2

2013年全国硕士研究生入学统一考试管理类专业硕士学位联考英语(二)真题试卷Section II Reading ComprehensionPart ADirections:Read the following four texts. Answer the questions after each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1. (40points)Text 1In an essay entitled ―Making It in America‖ the author Adam Davison relates a joke from cotton country about just how much a modern textile mill has been automated: The average mill has only two employees today, ―a man and a dog. The man is there to feed the dog, and the dog is there to keep the man away from the machines.Davidson’s article is one of a number of pieces that have recently appeared making the point that the reason we have such stubbornly high unemployment and declining middle-class incomes today is largely because of the big drop in demand because of the Great Recession, but it is also because of the advances in both globalization and the information technology revolution, which are more rapidly than ever replacing labor with machine or foreign workers.In the past, workers with average skills, doing an average job, could earn an average lifestyle. But, today, average is officially over. Being average is just wo n’t earn you what it used to. It can’t when so many more employers have so much more access to so much more above average cheap foreign labor cheap robotics, cheap software, cheap automation and cheap genins. Therefore, everyone needs to find their extra – their unique value contribution that makes them stand out in whatever is their field of employment.Yes, new technology has been eating jobs forever, and always will. But there’s been an acceleration. As Davidson notes, ― In the 10 years ending in 2009, factories shed workers so fast that they erased almost all the gains of the previous 70 years; roughly one out of every three manufacturing jobs – about 6 millions in total – disappeared.‖There will always be change – new jobs, new products, new services. But the one thing we know for sure is that with each advance in globalization and the I.T. revolution , the beat jobs will require workers to have more and better education to make themselves above average.In a world where average is officially over, there are many things we need to do to buttress employment, but nothing would be more important than passing some kind of G.I. Bill for the 21st century that ensures that every American has access to post-high school education.21. The joke in Paragraph 1 is used to illustrate .A. the impact of technological advancesB. the alleviation of jobs pressureC. the shrinkages of textile millsD. the decline of middle-class incomes22. According to Paragraph 3, to be a success employer, one has to .A. adopt an average lifestyleB. work on cheap softwareC. contribute something uniqueD. ask for a moderate salary23. The quotation in Paragraph 4 explains that .A. gains of technology have been erasedB. job opportunities are disappearing at a high speedC. factories are making much less money than beforeD. new jobs and services have been offered.24. According to the author, to reduce unemployment, the most important is .A. to accelerate the I.T. revolutionB. to ensure more education for peopleC. to advance economic globalizationD. to pass more bills in the 21st century25. Which of the following would be the most appropriate title for the text?A. Technology Goes CheapB.New Law Takes EffectC. Recession Is BadD. Average Is Over参考答案:ACBBDText 2A century ago, the immigrants from across the Atlantic included settlers and sojourners. Along with the many folks looking to make a permanent home in the United States came, those who had no intengtion to stay, and who would make some money and then go home. Between 1908 and 1915, about 7 million people arrived while about 2 million departed. About a quarter of all Italian immigrants, for example, eventually returned to Italy for good. They even had an affectionate nickname,‖ uccelli dipassaggio,‖ birds of passage.Today, we are much more rigid about immigrants. We divide newcomers into two categories: legal or illegal, good or bad. We hail them as Americans in the making, or brand them as aliens fit for deportation. That framework has contributed mightily to our broken immigration system and the long political paralysis over how to fix it.Crop pickers, violinists, construction workers, entrepreneurs, engineers, home health-care aides and particle physicists are among today’s birds of passage. They are energetic participants in a global economy driven by the flow of work, money and ideas. They prefer to come and go as opportunity calls them. They can manage to have a job in one place and a family in another.With or without permission, they straddle laws, jurisdictions and identities with ease. We need them to imagine the United States as a place where they can be productive for a while without committing themselves to staying forever. We need them to feel that home can be both here and there and that they can belong to two nations honorably.Accommodating this new world of people in motion will require new attitudes on both sides of the immigration battle. Looking beyond the culture new attitudes on both sides of the immigration battle. Looking beyond the culture war logic of right or wrong means opening up the middle ground and understanding that managing immigration today requires multiple paths and multiple outcomes, including some that are not easy to accomplish legally in the existing system.26.‖Birds of passage‖refers to those who_____.[A]find permanent jobs overseas[B]leave their home countries for food[C]immigrate across the Atlantic[D]stay in a foreign country temporarily27.It is implied in paragraph 2 that the current immigration system in the US_____.[A]needs new immigrant categories[B]has loosened control over immigrants[C]should be adapted to meet challenges[D]has been fixed via political means28.According to the author, today`s birds of passage want______.[A]financial incentives[B]a global recognition[C]opportunities to get regular jobs[D]the freedom to stay and leave29.The author suggests that the birds of passage today should be treated______.[A]as faithful partners[B]with legal tolerance[C]with economic favors[D]as mighty rivals30.The most appropriate title for this text would be_____.[A]Come and Go:Big Mistake[B]Living and Thriving:Great Risk[C]Legal or Illegal: Big Mistake[D]With or Without:Great Risk参考答案:DCDBCText 3Scientists have found that although we are prone to snap overreactions, if we take a moment and think about how we are likely to react, we can reduce even eliminate the negative effects of our quick, hard-wired responses.Snap decisions can be important defense mechanisms; if we are judging whether someone is dangerous, our brains and bodies are hard-wired to react very quickly, within milliseconds. But we need more time to access other factors. To accurately tell whether someone is social, studies show, we need at least a minute, preferably five. It takes a while to judge complex aspects of personality,like neuroticism or open-mindedness.But snap decisions in reaction to rapid stimuli aren’t excusive to the interpersonal realm. Psychologists at the University of Toronto found that viewing a fast-food logo for just a milliseconds primes us to read 20 percent faster, even though reading has little to do with eating. We unconsciously associate fast food with speed and impatience and carry those impulses into whatever else we’re doing. Subjects exposed to fast-food flashes also tend to think a musical piece lasts too long.Yet we can reverse such influences. If we know we will overreact to customer products or housing options when we see a happy face ( one reason good sales representatives and real estate agents are always smiling), we can take a moment before buying. If we know female job screeners are more likely to reject attractive female applicants, we can help screeners understand their biases – or hire outside screeners.John Gottman, the marriage expert, explains that we quickly ―thin slice‖ information reliably only after we ground such snap reactions in ―thick sliced‖long-term study. When Dr. Gottman really wants to assess whether a couple will stay together, he invites them to his island retreat for a much longer evaluation: two days, not two seconds.Our ability to mute our hard-wired reactions by passing is what differentiates us from animals: the dogs can thinks about future only intermittently or for a few minutes . but historically we have spent about 12 percent our days contemplating the longer term. Although technology might change the way we changed our nature. We will have the imaginative capacity to rise above temptation and reverse the high-speed trend.31. The time needed in making decisions may .A. vary according to the urgency of the situationB. prove the complexity of our brain reactionC. depend on the importance of assessmentD. predetermine the accuracy of out judgment32. Our reaction to a fast-food logo shows that snap decisions .A. can be associativeB. are not unconsciousC. can be dangerousD. are not impulse33. To reverse the negative effects of snap decisions, we should .A. trust our first impressionB. do as people usually doC. think before we actD. ask for expert advices34. John Gottman says that reliable snap reactions are based on .A. critical assessmentB. ―thin sliced‖ studyC. sensible explanationD. adequate information35. The author’s attitude toward reversing the high-speed trend is .A. tolerantB. uncertainC. optimisticD. doubtful参考答案:DACDCText 4Europe is not a gender-equality heaven. In particular, the corporate workplace will never be completely family-friendly until women are part of senior management decisions, and Europe’s top corporate-governance positions remain overwhelmingly male. Indeed, women hold only 14 percent of positions on European corporate boards.The European Union is now considering legislation to compel corporate boards to maintain a certain proportion of women-up to 60%. This proposed mandate was born of frustration. Last year, European Commission Vice President Viviane Reding issued a call to voluntary action. Reding invited corporations to sign up for gender balance goals of 40% female board membership. The Forte foundation in America has now flowed suit with its own list of ―board-ready women.‖ But Reding’s appeal in Europe was considered a failure: only 24 companies took it up.Do we need quotas to ensure that women can continue to climb the corporate ladder fairly as they balance work and family?―Personally, I don’t like quotas,‖ Reding said recently. ―But I like what the quotas do.‖ Quotas get action: they ―open the way to equality and they break through the glass ceiling,‖ according to Reding, a result seen in France and other countries with legally binding provisions on placing women in top business positions.I understand Reding’s reticence --- and her frustration. I don’t like quotas either; they run counter to my belief in meritocracy, governance by the capable. But, when one considers the obstacles to achieving the meritocratic ideal, it does look as if a fairer world must be temporarily ordered.After all, four decades of evidence has now shown that corporations in Europe as well as the US are evading the meritocratic hiring and promotion of women to top positions --- no matter how much ―soft pressure‖ is put upon them. When women do break through to the summit of corporate power --- as, for example, Sheryl Sandberg recently did at Facebook --- they garner massiver attention precisely because they remain the exception to the rule.Of appropriate public policies were in place to help all women --- whether CEOs or their children’s caregivers --- and all families, Sandberg would e no more newswarthy than any other highly capable person living in a more just society.36. In the European corporate workplace, generally _______.[A] women take the lead[B] men have the final say[C] corporate governance is overwhelmed[D] senor management is family-friendly37. The European Union’s intended legislation is _______.[A] a reflection of gender balance[B] a reluctant choice[C] a response to Reding’s call[D] a voluntary action38. According to Reding, quotas may help women ________.[A] get top business positions[B] see through the glass ceiling[C] balance work and family[D] anticipate legal results39. The author’s attitude toward REding’s appeal is one of _______.[A] skepticism[B] objectiveness[C] indifference[D] approval40. Women entering top management become headlines due to the lack of _____.[A] more social justice[B] massive media attention[C] suitable public policies[D] greater ―soft pressure ‖36. 细节题:选B,要含有男性的这个对象,男性主导37. 细节题:选B,选择有陷阱的,干扰项C。

Choose the most suitable answer from the given choices. Then mark the corresponding letter on the answer sheet with a single line through the centre.For the other threeincomplete sentences,you should complete them in a maximum of three words using information from the passage.Remember to write the answers on the answer sheet.Questions56-60 are based on following passae.My entry into Black women’s history wasunexpected but agreeable.In the preface to Black Women in America:An Historical Encyclopedia,I recount the story ofexactly how Shirley Herd(who,in addition to teaching in the local school system,was also president of the Indianapolischapter of the National Council of Negro Women)successfully provoked me into changing my research andwriting focus.Although I dedicate this volume to her and to her best friend,fellow club woman and retired primary schoolteacher Virtea Downey,Istill blush at the fact that I went to graduate school to become a historian In order to contribute to the Black Struggle for social justice and yet met her request to write a history of Black women in Indiana with reluctance.I had neever even thought about Black women as historical subjects with their own relations to a state’s history,and I thought her invitation and phone call extraordinarily intrusive.Only later did I concede how straightforward and reasonable had been her request to redress a historical omission.Black women were conspicuous by their absence.None of the social studies texts or state histories that Herd and Downey had used to teach their students made mention of the contributions of Black women.Since historians had left them out,Herd reasoned,only a “real”historian could pue themin,and since I was the only tenured Black women historian in the state of Indiana at that time,the task was mine.Herd rejected my reservations and completely ignored my admonitions that she could not call up a historian and order a book the way you drive up to a fast-food restaurant and order a hamburger.In spite of my assertions of ignorance about the history of Black women in Indiana and my confession of habing never studied the subject in any history course or examined any manuscript sources pertaining to their lives,Herd persevered.Black women,ashistorical subjects and agents, were as invisiable to me as they hadbeen toschool textbook writers.Undaunted by my response,Herd demanded that I connect(thankfully without perfect symmerty)my biology andautobiography,my race and gender,my being a Black women,to my skill as a historian,and write for her and for the local chapter members of the National Council a history of Black Women in Indiana.I relented and wrote the book,When the Truth Is Told:Black Women’s Culture and Community in Indiana,1875-1950,as requested,In the process,I was both humbled and astouned by the array of rich primary sorce materials Herd,Downey,and the other club women had spent two years collecting.There were diaries,club notes,church souvenir booklets,photographs,club minutes,brith,death,and marriage certificates,letters,and handwritten county and localhistories.Collectively this material revealed a universe I never knew existed in spite of having lived with Black women all of my life…and being one myself.Or perhaps more accurately,I knew a universe of Black women existed.I simply had not envisioned its historical meaning.56.The primary purpose of the passage is to show how the author______.A.discovered Black women’s history when she was in graduate schoolB.became a historian to help Black people in America achieve social justiceC.developed her research skills by undertaking a challenging projectD.came to view Black women as a worthy subject for historical analysis57.Why did the author initially respond to Herd’s request “with reluctance”?A.Because she knew that historians should avoid controversial subjects.B. Because there were too many other projects requiring her attention.C. Because she viewed Herd’s request as irrelevant and presumptuous.D. Because she knew that Herd had not been to graduate school.58. The author compared Herd’s demanding a history book to ______to indicate that she did not generally undertake projects on request.59. The author believed that historians should conduct research in areas in which they had expertise so she asserted that she was ______about the project.60.Herd and the other club women spent two years collecting______to prove that Black women contributed to society historically.Section B (10 points)In this setion,there is one passage followed by five questions.You should answer each question in a maxium of ten words using information from the passage.Remember to write the answer on the answer sheet.Questions61-65 are based on the following passae.In the past,hunting was necessity,with humans killingwild animaks for food and clothing.However,modernhunters generally hunt for one of two reasons:forsport,or because it’spart of their traditional culture.Canhunting ever be justified?Hunting for sport is popular all over the world.Every year in the United States,more than 12 million people go hunting ;and wealthy enthusiasts from around the world pay thousands to go on African safaris.While many recreational hunters eat the animal they kill,others simply do it for trophies.These so-called trophy hunters pay taxidermists to stuff and mount the dead animals,which they then display in their homes as souvenirs.So,should hunting for sport be allowed?No,says animal rigt group PETA.They believe animals have the right to live out their natural lives in the wild. And the group notes that hunted animals often escape after being wounded and are left to die slowly and painfully.Other anti-hunting activists argue that hunters prefer to kill the bigger members of a species,which oftenleaves the smaller ones behind to breed.As a result,the entire species slowly becomes weaker.Of course,many hunters diagree.They claim that responsible hunters follow a strict code of conduct,which includes never letting a wounded animal escape,and never taking a shot at an animal unless it’s going to be a clean kill.Hunters also agrue that their sport keeps certain species in check,preventing overpopulation.For example,they say that if waterfowl weren’t hunted,their numbers would grow too large,leading to outbreaks of fowl cholera,a disease dangerous to humans. Hunters even agrue that they’re helping endangered species.This is because many countries reinvest hunting revenue (from permits or safari fees)back into animal conservation.For example,some of the money that Zimbabwe earns from foreign elephant hunters is put back into elephant conservation.As a result,Zimbabwean elephant numbers are actually steadily increasing.However,conservationists saythat killing animals in order to save themis hypocritical and that there are otherways to protect endangered wildlife.But what about traditional cultures who still hunt for their food?The Inuit people have lived in the Arctic for thousandss of years and their traditional diet includes the endangered bowhead whale.Local laws allow them to kill a limited number of bowheads a year and many Inuit argue that traditional societies must adapt and drop endangered species from their diets.Questions61. Generally,what are the two reasons for hunting?62. What do trophy hunters pay taxidermists to do?63. What do hunters argue that hunting can help prevent?64.What could be the consequence of not hunting waterfowl?65.What is Inuit people’s code of conduct regarding hunting?Section C (10 points)In this setion,there is one passage presented as a conversation between Mike,Jack and Peter,followed by a summary which is an email sent to Mike’s friend,Paul.You should complete the email below suing no more than three words for each blank from the passage.Remember to write the answer on the answer sheet.Questions 66-70are based on the following passage.“I’ve just heard that Mike’s moved jobs,”said Jack toPeter.”The strange thing is that he’s moved to a much smallerfirm and he’s usually so aambitious.It doesn’t sound like thekind of thing he’d do.Moving to a larger firm would be muchmore his style.”Peter replied,”I was talking to him briefly last night,but hedidn’t have time to give me any details.He said he’d tell me allabout it next time we meet.I gather that he still liked the workhe was doing,but the marketing department,where he worked,had become a revolving door.A lot of people left before Mike did and their replacements are saying no time at all.That must be very unsettling for everyone.”Just then,Mike walked in and they asked him what had happened to make him change jobs.He began to tell them the background to his move. “To put it in a nutshell,it’s all the fault of the new marketing director.About six months ago,management decided that as a company we didn’t have a high enough profile and they got rid of Jeff Jones,who was head of marketing,and appointed someone to improve the image of the company.Unfortunately,the new broom is one of those people who takes an instant dislike to some people and sets out to make their lives a misery.I don’t know what he’s done for the public image of the firm,but morale has hit rock bottom.It’s particularly sad because Jeff Jones was a good boss and it was a very happy department when he was there.”Peter said,”That’s dreadful.It’s very difficult to work under such circumstances.How did you get on with him?”“I got on with him all right,I suppose,but his mood could change from one minute to another.None of us knew where we stood with him.I decided early on to get out while the going was good and was lucky enough to get a job with Smith&Jones.They’re a much smaller company,but you can see that they’re going place.They treat their staff well and so they stay around.”“It might be in the end a good career move,then,” said Jack.”Perhaps he did you a favour,after all.”“Certainly,”said Jack. “I’ve taken a cut in salary at the moment,but looking ta the big picture I can see that my promotion prospects are much better.”“You wouldn’t go back to your old job if this new man left,then?”asked Peter.“After the way management let him treat us?” asked Mike.”You must be joking!”Hi Paul,I’ve just changed jobs.I’ve moved to(66)______,Smith and Jones,and will take a pay cut but it’s wroth it as the (67)are much better here.The main reason for leaving the old company is that the new marketing director had turned the office environment from a happy one to one with low(68)______.If he disliked someone,he would make(69)______.Though I(70)______him,I couldn’t be sure when would turn on me.So I decided to leave.Wish me luck.Cheers,MikeSection D (10 points)In this setion,there is one passage followed by five questions, Remember to write the answer on the answer sheet.Questions 71-75are based on the following passage.The end of financial year is approaching and,with it,the AGM,when we will have to give an account of the year’s proceeding to our shareholders.As usual,at this time of year,Iam sending a copy of this informal end-of-the-year report to all members of the sales force.I hope that you will all find it useful and that you will let me know if you have any comments.I value your input.We started this year with a major new product and we really hit the ground running.Our sales for the first quarter of the year were very impressive and,indeed,broke all records.(74)This wasparticularly heartening as this occurred at a time when many of our competitors were feeling the pinch.Indeed,there was talk among economic experts of an impending recession and even of economic meltdown.Fortunately,this gloom and doom did not materialize.It was good that we were able to buck the trend,but as I said,we had a major new product and one ,indeed,that is popularly believed to have broken the mould of kitchen equipment.Therefore,it would have been extremely surprising,not to say distressing,if we had not achieved substantial sales with it.What is rather distressing is that the rest of theyear did not live up to the promise of the firstquarter,this despite the fact that the financial stateof the country improved in the course of theyear.(75)To some extent,of course,it would nothave been realistic to expect that peak level salescould be sustained throughout the year. Somefalling-off was worse than had been anticipated.This gave us all food for thought and,fortunately,we were able to learn from the experience.Indeed,I think we should regard the introduction of the new product as a useful learning curve from which all departments have benefited.The whole programme of product launching has been assessed and revised where appropriate.We shall all be better prepared next time.On the whole,this was a successful year and we hope to build on that success in the coming year.Thank you all for your contribution to this success.Get ready to do even better next year!For Questions 71-73,markY(for YES)if the statement agrees with the information given in the passage;N(for No)if the statement contradicts the information given in the passage.71.The sales report was usually sent out in the middle of the financial year.72.The company was not affected by an economic downturn in the first quarter.73.The company gained useful experience on how to launch and sell a new product.For Questions 74 and 75,translate the underlined sentences of the passage into Chinese.Remember to write the answer on the answer sheet.74.___________________________________________________75.___________________________________________________Part V Translation (10 points)Translate the following sentences into English, using the hints given in brackets. Remember to write the answer on the answer sheet.76. 如今,许多城市居民喜欢到海滨从事水上运动。

2013年北京市中考英语I bought a jasmine plant for my office阅读理解答案2013年北京市高级中等学校招生考试六、阅读下列短文,根据短文内容,从短文后各题所给的A、B、C、D四个选项中,选择最佳选项。

Relation between you and food.D. Films that aren’t really about Canada.49 . What is Black sheep and Uncle Bob about?A. American films.B. Family stories.C. Food.D. Banking.BI bought a jasmine plant for my office. When I bought it,I was told it would bloom(开花)and the sweet smell would fill my office. I had the plant for two months, and every day I looked at it, but there weren‟t any flowers or pleasant smell. I was not happy, so I gave the plant to my friend Linda.One day, another friend Mary called and invited me to her office. When I walked in, her jasmine flowers surprised me.I reached out to touch the flowers. Mary cut some and gave them to me. I couldn‟t help smelling them. Surrounded by the sweet smell of only a handful of these flowers, I suddenly understood something.Mary bought her plant the same time I did. It took a year for her jasmine to bloom. I was so impatient for mine to bloom; regretfully, I gave it away.In a way my life is like the jasmine plant. I need to be patient and let things happen.Last Sunday Linda told me that she was going abroad the next week. Before she left, she returned the plant to me. This time I am going to wait. I have learned that when we want something in our life, we have to be patient. I am slowly learning to have that patience to wait for my jasmine to bloom.50. Before she gave the jasmine away, the writer had it for .A. one dayB. one year C . two weeks D. two months51. When the writer saw Mary‟s jasmine, she felt____________ .A. unhappyB. peacefulC. hopefulD. surprised52. What has the writer learned from her experience?A. Patience is needed in life.B. Flowers can make life better.C. Friendship is necessary for us.D. Jasmine can be a wonderful plant.CAssertiveness is the ability to confidently express your opinions, feelings,attitudes, and rights, in a way that doesn‟t infringe(侵犯)the rights of others.Many of us are taught that it is not nice to consider our own needs above those of others. If someone says or does something that we don‟t like, we should just be qui et and try to stay away from that person in the future.Why is Assertiveness important?If you don‟t know how to be assertive, you might experience:•Depression - Anger, a sense of being helpless, hopeless,or of having no control over your life.•Resentment - Anger at others for taking advantage of you.•Frustration - Why did I allow that to happen?Most people find it easier to be assertive in some situations than in others. This makes perfect sense. It‟s a lot easier to hold your ground with a stranger than with someone you love. But the more important the relationship is to you, the moreimportantit is to be assertive. Assertive behavior leads to increased respect from others!But before you decide to act assertively, you have to decide if you can livewith the results. Although assertive behavior usually will result in a positiveresponse (积极的回应),some people might react differently.How to be effectively(有效地)assertive:•Use “I” statements. Keep the focus on the problem you‟re having. “I‟d like to be able to tell my stories without interruption.” instead of “You‟re always interrupting my stories ! “•Use facts, not opinions. “Did you know that shirt has ahole?” instead of”You‟re not going out looking like THAT, are you?”•Express ownership of your thoughts, feelings, and opinions. “I get angry when he breaks his promises. “ instead of “He makes me angry. “• Make clear and direct requirements. Don‟t invite the person to say no. “Will you please?” instead of‟W o uld you mind...?” or “Why don‟t you...?”•Keep repeating your point. Use a low level and pleasant voice. Don‟t try to explain yourself.53. The writer probably agrees that---____________.A. you should consider others‟ response before you act assertivelyB. you should be assertive if you want to get good marksC. assertiveness is the ability to infringe others‟ rights .D. assertive behavior will bring you bad feelings54. The expression “hold yourground” probably means “_________________”A. reach an agreementB. insist on your pointC. keep your wordD. keep on fighting55. Which of the following helps you to be effectively assertive?A. Explaining yourself in a soft and sweet voice.B. Expressing ownership of oth ers‟ thoughts.C. Making requirements directly and clearly.D. Using your opinions instead of facts.DThe willful blindness in hockey toward concussions (头部撞击) has dropped. Hockey Canada has followed the lead of USA Hockey in preventing bodychecking (身体拦截) below age 13. A bad head injury of Sidney Crosby, the hockey‟s greatest star, opened the eyes of hockey people everywhere. This country‟s children have been facing similar danger at early ages, and Hockey Canada had to deal with a deep worry in the minds of Canadians to make the rule change. The liking for bodychecking from an early age is part of what makes Canadian hockey what it is.The change in rules should be taken as a chance to draw special attention to skill development in an environment free of danger. It may also control the loss of thousands of young players who don‟t enjoy that environment.For years, many Canadian hockey parents and coacheshave insisted that bodychecking at early ages is necessary to ensure that players can do it safely at older ages. True or not, there may be a safer way to teach hitting than to make younger players pay a price for it in head injuries. When USA Hockey changed its rules for the 2011-2012 season, it also created bodychecking-education programs that will be mandatory(强制的) for all coaches, including those teaching players in the pre-checking ages. And it began to encourage more “touch” - without real bodychecking - from 9 t0 12. It also made the rules for 13 and up stricter. The USA is trying to show that it‟s possible to teach hockey protective skills without putting11 and 12-year-olds in greater danger. It‟s worth the try.Hockey Canada has taken serious steps to do away with hits on the head. However, it‟s hard to change a sports culture so connected with who we are as a country. Too often, bodychecking has been used to try to separate a player from his head rather than from the ball. Children were paying a price for this country‟s love of the game.There are always changes in Canada‟s ga me, and the change in the bodychecking age sends the clearest message yet to coaches and parents that player safety is paramount(至上的) in the game.56. We can tell that the problem of bodychecking in Canada____________.A. is controlled strictlyB. is taken more seriously nowC. is caused by players‟ carelessnessD. is connected with players‟ interest57. What does the writer want to tell us in Paragraph 2?A. The safe ways of controlling the loss.B. The steps of drawing special attention.C. The possible results of changing the rules.D. The methods of improving the environment.58. What can we learn from the passage?A. The USA found a safer way to teach bodychecking.B. Bodychecking-education programs in the USA are successful.C. Bodychecking is a good way to value players‟ skills in the USA.D. The USA has tried to create an environment of less bodychecking.59. What is probably the best title‟ for this passage?A. Which is more important?B. How do we change the rules?C. Why is hockey a dangerous game?D. When should bodychecking be prevented?七、阅读短文,根据短文内容,从短文后的五个选项中选出能填入空白处的最佳选项。

I often want to play games and don’t listen to my teachers carefully in class.As a saying goes, “No pains, no gains.” I do know if I really want to realize my dream to the university, I have to work hard at all subjects. From now on, I am determined to make full use of my time, attending my class attentively, reading wildly, completing all the homework and doing sports to keep healthy.I believe, only by working hard at all subjects can I make my dream come true.。

桐叶封弟辨[唐]柳宗元古之传者有言,成王以桐叶与小弱弟戏[1],曰:“以封汝!”周公入贺。

王曰:“戏也!”周公曰:“天子不可戏。

”乃封小弱弟于唐。

吾意不然。

王之弟当封邪,周公宜以时言于王,不待其戏而贺以成之也。

不当封邪,周公乃成其不中之戏,以地以人与小弱者为之主,其得为圣乎?且周公以王之言,不可苟焉而已,必从而成之邪?设有不幸王以桐叶戏妇寺[2],亦将举而从之乎?凡王者之德,在行之何若;设未得其当,虽十易之不为病。

要于其当,不可使易也;而况以其戏乎!若戏而必行之,是周公教王遂过也。

吾意周公辅成王,宜以道从容优乐,要归之大中而已,必不逢其失而为之辞,又不当束缚之,驰骤之,使若牛马然,急则败矣。

且家人父子,尚不能以此自克;况号为君臣者邪?是直小丈夫 者之事[3],非周公所宜用,故不可信。

或曰:封唐叔,史佚成之[4]。

(选自天津古籍出版社《古文观止》)【注释】[1]【题解】“辨”是一种用于辨析事物的是非真伪而加以判断的论说文体。

[2]成王:姓姬名诵,西周初期君主,周武王之子,十三岁继承王位,因年幼,由叔父周公摄政。

小弱弟:指周成王之弟叔虞。

[3]妇寺:宫中的妃嫔和太监。

[4](quē缺):耍小聪明的样子。

[5]史佚:周武王时的史官尹佚。

史佚促成桐叶封弟的说法,见《史记·晋世家》。

(1)本文虽为“辨”,但本文的重点不在于“辨”,而是围绕重臣应如何辅佐君主这一中心发挥议论,请用自己的话概括本文作者所要表达的主旨。

(4分)(2)有人认为柳宗元这篇文章论辩反复曲折,波澜起伏,闪耀着深刻的思想光芒,请结合文本进行分析。

(6分)答案:(1)柳宗元的这篇文章,对臣子把君主随便开的一句玩笑话当作金科玉律,绝对服从的荒唐现象进行了尖锐地批评,指出“凡王者之德,在行之何若”,对统治者的言行,要看它的客观效果如何,不能拘执盲从。
